That's an interesting product, and I can see how it can add rigidity. It would be nice if there was a way to get a visual perspective (or actual measurements) of how much it helps. Gone are the days where you could jack up one corner of a Mustang and flex the chassis so much the door wouldn't open.

I'm also curious to know how much these ACTUALLY help. I have the hop stopper kit, but not installed yet. I get the feeling I am going to end up replacing LOTS of the stock suspension w/ all aftermarket it looks like lol.

Thanks, Steve! To provide a bit more info, without these braces installed, if you were to remove your rear IRS subframe bolts the entire assembly will hang down over 1” from the chassis.

With the braces installed and you remove the same bolts, the entire sub-assembly hangs down less than ¼”.

It really helps the rigidity of the subframe.

do these only come in the silver? Any forum discount by chance?

But that doesn't match my Steeda sway bars

Are these meant as a different option at stopping wheel hop than the bushing supports? Or are they meant to be complimentary? Any increase in NVH with these?

 

[SID297]

I'm thinking more and more about adding a set of these.

is this 100% ONLY structural flexing, or does this also include flex due to the pliable subframe bushings that would otherwise be non-existent with solid subframe bushings? if the solid subframe bushings(like the ford racing pieces) would reduce flex equally as well, they seem like the better option(NVH aside, which these braces with factories bushings totally win with) since they make improvements in multiple areas.

Will these help with cowl shake on a Vert?
